Unit 3 Flashcards
Genetic Diversity
a biological variation that occurs in a species (wolves fur being different colors)
Species Diversity
Species richness + Species evenness.
(Wolves, Bears, Elk and Bison living in Yellowstone.)
Ecosystem Diversity
The amount of different ecosystems across a certain area of land. (Northern Washington having beaches, oceans
2 main roles of biodiversity
Improves stability of ecosystem and ecosystem services
HIPCO
Habitat loss, Invasive species, Pollution, Climate Change and Over harvesting
Specialist Species
A species that depends on one certain thing to live such as food or habitat (Pandas and bamboo)
Generalist Species
Do not rely on a certain food or habitat to live (Rats)
Invasive Species
A species that is not native to an area that is harming native ecosystems (Asian Carp)
Keystone species
A species that has a large effect on its ecosystem (Beavers)
Indicator species
A species that can indicate an environmental value (Coral, indicates water temp)
Endemic Species
A species that lives in limited area (Lemurs)
Species Richness
The total amount of different species in an area
Species evenness
The distribution in abundance of different species in a certain area
ESA
The Endangered Species Act (ESA) is a 1973 U.S. law protecting at-risk species and their habitats to prevent extinction.
SSP
The Species Survival Plan (SSP) is a zoo and aquarium program to breed endangered species and maintain genetic diversity.
CITES
CITES (Convention on International Trade in Endangered Species) is a global treaty that regulates the international trade of endangered plants and animals to prevent species extinction.
Wildlife Corridor
A designated area that connects wildlife populations that have been separated by human activities or structures
Exploitation
The overuse of natural resources, leading to harm to the ecosystem
Conservation
Seeking the proper use of nature to use goods but not decline the ecosystem
Preservation
Seeking no use of nature, leaving it alone.
Restoration
Restoring something to what it was before
Resistance
The ability to be unchanged
Resiliance
The ability to recover from changes
Intermediate Disturbance Hypothesis
ecosystems experiencing moderate levels of disturbance (such as fires, storms, or human activity) tend to have higher biodiversity than those with low or high levels of disturbance.
